. Still another object of this invention resides in the provision ofsuch a gangway having intermediate steps which are readily removable toprovide a selective intermediate landing to the vessel.

Still other objects reside in the provision of a safety means wherebypassengers may ascend to the upper deck of the vessel without thepossibility of injury in the ascension.

Still further objects in the combinations of elements, features ofconstruction, and arrangements of parts, all as will be more fully shownin the accompanying drawings and disclosed in the accompanyingspecification.

Having reference now to the accompanying drawings, other objects will inpart he pointed out and in part be shown.

In the drawings:

Fig. 1 is a perspective v-iew disclosing the gangway or gangplank of theinstant invention in extended position.

Fig. 2 is .a similar view disclosing the gangplank in retractedposition.

Fig. 3 is a rear elevational view of the construction of Figs. 1 and 2showing the steps in the gangway retracted position.

Fig. 4 is a sectional view taken substantially along the line 4-4 ofFig. 3 that is viewed in the direction indicated by the arrows.

Fig. 5 is a sectionaI view taken substantially along the line 5 5 ofFig. 1 as viewed in the direction indicated by the arrows.

Fig. 6 is a top plan View of the construction disclosed in Figs. 1 and2.

Fig. 7 is a sectional view taken along the line 7-7 of Fig. 5 as Viewedin the direction indicated by the arrows.

Fig. 8 is a top plan view of a constructional detail; and

Fig. 9 is a side elevational view of the struct disclosed in Fig. 8. i

Similar reference characters refer to similar parts throughout theseveral views of the drawings.

Having reference now to the drawings in detail there is generallyindicated at 10 a gangway comprised of side rails 11 each carryinguprights 12 which in turn carry guide wires or ropes 13 formingrailways. Between side rails 11 extend a plurality of removable steps14, each having an enlarged rear edge 15 formed with a longitudinalchannel 16 (see Figs. 3, 4 and 7) the enlarged edge being adapted toseat in grooves 17 cut in the inner edge of side rails 11. Transverserods 18 extends through s ICC suitable bores in the outer sides of siderails 11 and are held in place, seated in channels 16, by means of nuts20.

Gangway 10 has slidably mounted thereon a bracket or hanger 21 ofgenerally U-s'hape extending across the rear and sides of the gangway 10and connected across the front thereof by a rotatably mounted bar or rod22 from which extend arcuate fingers 23 biased downwardly to engagebeneath a selected step 14 and against the top edge of the bight ofhanger 21, by means of coil springs 24 surrounding rod 22.

At the opposite ends of rod 22 are positioned bolts 25 which carryL-shaped hanger members 26 which are slidably mounted on the legs 29 ofa generally U-shaped support member 30, the hangers 26 being retractedagainst inward movement on legs 29 by means of slidably adjustablecollars 31.

The inner ends of legs 29 are fixed to a rotatable shaft 32 journaled inbrackets 33 mounted on the deck 34 of the vessel. Rod or shaft 32carries at one end an arm 35 on which is movably mounted the eye of abolt 36 which is connected at its other end, by means of a turnbuckle37, to a second eye bolt 38, the other end of which is connected to anarm 39 extending from the top of a tubular member 40 pivotally mountedon deck 34 rearwardly of the adjacent bracket 33. A second turnbuckle 41connects eye bolts 42 and 43, one of which has its eye fixed to the deckas at 44, and the other of which has its eye connected to a second arm4S which has an upper eye engaging arm 39.

It will now be seen that tightening of turnbuckle 37 will swing thegangway through arm 35, shaft 32 and member 30 from the extendedposition of Fig. 1 to the retracted position shown in dotted lines inFig. 2, and that tightening of turnbuckle 41 will tilt tubular vmember40 to the inclined full line position of Fig. 2, for full retraction.

As the turnbuckles 37 and 41 are tightened, the shaft 32 is rotatedthrough the movement of arm 35 and post 40 and the member 30 is thusswung from the horizontal position of Fig. l to the vertical position ofFig. 2. During this movement, the gangway is simultaneously manuallymoved upwardly, while subsequently the successive steps 14 ratchet overthe spring ngers 23 and the parts assume the nal position as shown inFig. 2. A securing turnbuckle and bolt assembly 49 (see Fig. 2) may beconnected between the lower end of gangway 10 and deck 34 to securegangway 1i) in full inboard position.

When it is desired to enter the ship on a lower deck, a selected numberof steps 14 are removed, and an extensible platform 50 swingably mountedas at 51 on the side of the ship may be extended to the top step to beused. Platform 50 comprises two plates 52 and 53, the latter beingprovided with reverted edges 54 so that the former is contained withinthe edges 54 and plate 53 is thus extensible and retractable relative toplate 52. A series of threaded apertures 55 are provided along the sidesof both plates 52 and 53, and when engaged by the threaded ends ofuprights 56 serve to hold plates 53 and 52 in a desired position ofadjustment (see Figs. 8 and 9). Upright 56 also serves to support aguard rail 57. Gangway 10 is preferably provided at its lower end with afoot plate 58.

From the foregoing it will now be seen that there is herein provided animproved gangway for ships or the like which accomplishes all of theobjects of this invention and others including many advantages of greatpractical importance and commercial utility.
